"Valve will be announcing a major update to the software development kit for PC users and downloadable content details for the Xbox 360 "very soon", a company spokesman told Kotaku today.

The new details, first hinted at in our December in-game interview with Valve's Chet Faliszek, could be announced as early as next week.

Valve declined to offer up anymore details about what the SDK update and DLC might include, but speaking with Faliszek in late December he hinted that new content might include opening op all multiplayer maps to versus mode on the console and "other things."

I'm still keeping my fingers crossed that Valve will be opening up machinima tools in the SDK."
